V TANK H EATER- AND WATER GIRCULATOB;

I Application fil ed December 6, 1921. Serial No. 520,359.

To (ZZZ whom it may concern:

Be it known'that I, ALBERT H. Os'rnaivonn, a citizen of the United States, and resident of Panora, in the county of Guthrie and State'oflowa, have invented a certain new and useful Tank Heater and VVater Circulator, of which the following is a specifi cation. y

The object of my invention is to provide '10 a tank heater and water circulating device of simple, durable andinex'pensive construction which may be easil and quickly placed into position in a stock Watering tank, and when so applied will e liiciehtly and uniforml'y heat the water within the tank.

A further object is to providein connection with that type or tank heaters which is adapted to be placed inside or an open stock Watering tank for thepurpose of preventing the water from freezin new and improved means for causing the water adjacent to the outer walls ofth'e tank to circu late in such a manner that it will not freeze to said walls; v p

A further object is to provide a tank heater adapted to burn liquid fuel and so arranged that the temperature ofthe heater may be accurately and easily obtained while in position in the tank.

These and other objects will be apparent to those skilled in the art. l r

'My invention consists in the construction,

arrangement and combination of the various parts of the --'device, whereby the objects con- 3 7 fully set forth,- pointed out in my claims, andrillustr'ated in the accompanying' drawing's, in which:

Figure 1 is a planview of a stock Watering tank showing the manner in which my improved heating device is mounted therein, the said heating device'liaving a portion of its top broken awayto'show the interior construction.

Figure 2 is a vertical longitudinal sectional view of my improved heater. Figure 3 is a transverse, sectional view taken on the line 3+3 of Figure 2. p

Figure 4 is a detail view of theloil burner used in connection with my. improved heater I p Figure 5 is a detail viewof one end of the-heating coil showing' 'tlie manner in which it is secured to the body portion of the beaten, i r

templated are attained, as hereinafter more Figure 6 is a detail sectional view taken on the line 6-6 of Figure 1.

The numeral 10 indicates the bottom of an ordinary stock Watering tank having a cylindrical and vertically arranged wall 11, which is illustrated for the purpose of showing the manner in which my improved heater is applied.

My improved heater comprises a "substantially rectangular body portion 12 having side members 13, a top member 14, a bottom member 15 and one end member 16.

The end member '16 is provided with a centrally arranged opening 17. An elbow 18 is secured to the end member 16 so as to register with an opening 17, by means of suitable rivets or bolts 19, and is seecured in such a manner that a water tight joint is formed between said elbow and said end plate.

The upper end of the elbow 18 is provided with an upwardly extending pipe 20 of such length that its upper endwill extend above the water level within the tank,

the level oi the water being indicated by the line 21, in Figure 2.

The pipe 20 forms a sort of chimney for removing the products of combustion from the burner, to be described.

The opposite end of the body portion "from the plate 16 is provided withflanges or lugs 22 for the purpose of securing one end of an'inc'lin'ed draft pipe 23 in position adjacent thereto by means oi rivets or This pipe 23 is of such length that its upper end will extenda considerable dis tanceabove the water line 21. l

The lower end of the pipe 23 andthe front end of the body portion 12 should be joined together so as to form 'a water tight joint to prevent water from entering the said body portion.

Secured in the front end ofthe body portion 12, I have prov ded a plate which is provided- W'ith an upper vertical portion and a horizontally arrangedandrearwardly extendin portion 26, and downwardly extending portion 27 adjacent to the front edge of the member 26. V The lower edge of the member 27 i provi'ded with a forwardly extending portion 28 which serves as a base to support the member 25, the Member 25 being so arranged that it may be removed from the body poring 29 for the purpose of providing means through which the burner may be lighted. A damper 30 is pivotally connected to the plate 25 in such a manner that it will swing to position to close the opening 29.

Secured upon the member 26, I have pro vided a body portion 31 of a burner, which body portion comprises substantially a pipe- T having each end closed by means of plugs 32, one of the plugs 32 being designed to receive one end of a "fuel supply pipe which extends rearwardly, thence curved upwardly and forwardly and passes through I an opening in the plate 25, and upwardly through the tube 23having its upper portion secured to the top of the tube by means of a clamp 3 1. The upper end of the pipe 33 is provided with a pet cook 35 mounted in the bottom ofa supply tank 36, the tank 36 being secured to the upperforward edge of the tube 23. The curved portion of the lower end of the tube 33 is secured in position by means of braces 37 secured to the plate 26. p 7

- A burner cap 38 is securedvin the upwardly extending opening of the T 31 and designed to rest immediately below the forwardly extending portion of the curved portion 33 so that the fuel may, be heated and vaporized before it enters the chamber of the member 31. Air is admitted to the burner through an opening 39 in the plate 26. V

the construction just described, it will be seen that I have provided a burner which will supplyheatto the interior of thebody portion 12 and will heat the water sur: rounding the said body portion in substantially the same mannen ashas heretofore been employed in similar tank heaters, but considerable difficulty has been experienced in heaters of this class due to the fact that the heater is generally set near the center of the tank and central portion of the water lwithin the tank becomes heated and the ice above the heater will be thawed, but 'the ice will be permitted to form on the innerface of the wall 11 and over the tOp of the outside edges of the top of the water.

These tanks are usually of considerable diameterv and the stockdrink from the outer edge of the tank which is usually frozen over to such a distance that the stock are unable; to reach the thawed portion in th center.-.-. i v 7 To. overcome'this difliculty, Ihave pro- 7 5 yided means for circulating the water with- 111 the tank in such a manner that the walls plate 13."

of the tank will receive a portion of the heated water, and thereby prevent ice from forming. V

For accomplishing this purpose,I have provided a heating coil 39 within the body portion 12. This coil comprises a pipe hav-- ing'one end extending through one of the p side members 13 near the front and the bottom thereof. This'pipe thence bends upwardly and forwardly to a point above the burnenmember 38. The pipe is then bent outside otthe; plate 1 3and held in position by means of a lock washer 42. This pro- An elastic washerel is provided for the vides means for rigidly-securing both ends 7 of the: coil 39 'into its respective side By removing the lock washer 42 and then tilting the coil 39? with one of its side edges upward and the other one downward, the

ends of the c0il39? may be drawn in through the openings, after which the coil '39? may belremoved throughthe front'end ofthe body portion.

plates -43 which are secured to the transversely arranged portions of the coil 39 in such a mannerthat the heat from the burner 38-maym'ove through thebody portion 12 in a zig zag: manner until it reaches. the outlet pipe 20. V 1 7 Secured 'to the outwardly extending portion of the rear end of the coil 39?, I have provided a pipe 4:4: having the shape ofa semi-circle, and of such diameter that its free end will; lie parallel with the wall 11 and comparatively close'thereto. The said outer end should extend slightly upwardly from its fixed end, the said outer'end being I have arranged a numbergof deflector supported by means of legs/15, shown in, 7

detail in Figure 6. a a A By this arrangement, it will beseen that if the body portion'121s placed in-the tank as shown in Figure 1, and the fuel from'the burner 18 is ignited, the interior of the body portion 12 will become. heated, and also the 00il39.;

The heating of the coil 39 will cause the water-to enterthe lowerendof thecoil 39* and be discharged through the 'outer end of thepipe 4 1 in such a manner that the current of water will be caused to circulate adjacentto the wallll of the tank and in an anticlock'wise direction, as shown in Figureld Y V The body portion of'the heater member 12 Wlll extend substantially transversely in the path of travel of the current, and thereby cause a large portion of the cold water from the wall 11 to engage the said heated body portion, and become heated.

By this arrangement, I have found that a very uniform temperature may be obtained throughout the tank with a comparatively small fuel consumption, as all of the heat from the burner is applied to the cooler water which prevents it from freezing while With the ordinary burner, the heated water rises to the top and center of the tank, and a large portion of the heat of which is radiated to the outside atmosphere above the Water in the tank.

It will also be seen that the temperature may be regulated by controlling the valve 35, and that'the burner may be easily and quickly removed for cleaning or repairing when necessary, and also the heating coil may be easily and quickly removed.

It Will, therefore, be seen that I have provided a tank heater and water circulating device of simple, durable and inexpensive construction which may be easily and quickly installed orremoved from the tank when it is desired, and which will very efliciently and uniformly heat the water within the tank when in operation I claim as my invention:

1. The combination of a tank with a water heater having a body portion of substantially a rectangular shape and arranged with its longitudinal axis radial within the tank, means for supplying heat to the interior of the body portion, a circulating coil within said body portion having each of its ends communicating with the water within the tank and surrounding said body portion, the discharge end of said coil being provided with a curved pipe having its discharge at the opposite side of the tank from which the body portion is mounted, and in such a manner that water being discharged from said pipe willfiowrin a circular manner adjacent to the wall of said tank. and cause the water Within the tank to travel transversely over the saidbody portion.

2. A heater for stock watering tanks comprising a substantially rectangular body portion having a bottom, top and side walls and one end wall provided with an opening, an elbow secured to said end wall in communication with said opening, an upwardly extending discharge pipe in communication with said elbow, a draft pipe secured to the opposite end of said body portion extending upwardly and forwardly, a detachable plate in the forward end of said body portion, a burner secured to the inner face of said plate, a supply tank on the upper end of said draft pipe, a pipe communicating with said supply tank and said burner, a heating coil above said burner and within said body portion having one end communicating with the outside of said body portion near its lower side, and its opposite end communicat ing with the exterior of said body portion near its top side, a circulating tube in com munication with the upper end of said heat ing coil, and means for supporting the outer end of said tube.

3. A tank heater comprising a hollow bodyportion designed to be entirely submerged in liquid, means for supplying heat to the interior of said body portion, a coil detachably secured to the interior of said body portion and having its ends in communication with the liquid surrounding the outside of said body portion, an auxiliary circulating coil secured to the discharge end of said heating coil having its discharge end so arranged that the liquid in which the heater is submerged will be moved in a circular path in such 1 manner as to travel over the said body portion while in movement.

4. A tank heater comprising a hollow body portion designed to be entirely submerged in liquid, detachable means for sup porting a burner within said body portion, upwardly extending means for supplying air to said burner having its upper end ex 7 tending above the liquid level, a second pipe in communication with said body portion for removing the products of combustion from said burner having its upper end above the liquid level, a fuel tank mounted on the upper end of said supply pipe, a pipe in communication with said fuel tank extending downwardly through said air supply pipe and communicating with said burner, a heating coil detachably secured within said body portion above said burner having its ends in communication with the liquid surrounding said body portion, an auxiliary circulating pipe in communication with the discharge end of said heating coil, and deflector plates secured to said heating coil.
